Apologies if this is the wrong area to ask, but I have a question with respect to interpreting an old NHBC inspection report.
The report contain last the statement “10 R D NOT FOLLOWED, A WALLS” and “10 R D NOT FOLLOWED, B FLOORS” throughout the report.
Does anyone know what “R D” refers to in this context?
The report is from 2006/ 2007
Cheers!
